Which atom is the largest
K
K+
Ca
Ca2+
Li

Explanation:

K: 2, 8, 8, 1 but 19p+

K+: 2, 8, 8 but 19p+

Ca: 2, 8, 8, 2 but 20p+

Ca2+, 2, 8, 8 but 20p+

K and Ca are larger than their corresponding ions because of one more energy level, so Li is the smallest.

K and Ca have the same no. of electron shells but K has less p+ than Ca. so the attraction between electron and p+ in K is less than that in Ca. Therefore, K is larger than Ca.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
